I'm trying to disable DDE for clicking URL links. Searching for help, I've found that file type "URL:HyperText Transfer Protocol" should be listed in the Tools->Folder Options->File Types tab of file explorer. However, on my system I only have "URL" file type (as extension).
So I go to the registry and the file type is there, but I don't know how to disable DDE. There is a "HKEY_USERS\S-1-5-21-1220945662-789336058-1801674531-14775\Software\Classes\http\shell\open\ddeexec" key but I don't want to cause damage.
My question: how to disable via registry or alternatively enable this on the File Types tab?
